Learn what CCA (Cold Cranking Amps) means and why it matters for your car battery's cold weather performance.

432 views

CCA (Cold Cranking Amps) is a rating used in the battery industry to define a battery's ability to start an engine in cold temperatures. Specifically, it measures how many amps a battery can deliver at 0°F for 30 seconds while maintaining a voltage of at least 7.2 volts. Higher CCA ratings indicate better performance in cold weather, which is crucial for reliable vehicle starts in winter conditions.
